JERUSALEM (JTA) — Rioting erupted at a Paris memorial for a haredi Orthodox woman who is believed to have been pushed out of her third-floor apartment by a neighbor to her death.

An estimated crowd of 2,000, mostly French Jews, attended the rally Sunday outside the home of Sarah Halimi. The event became contentious when some young Jews, reported by Israel Radio to be from the Jewish Defense League, began arguing with Halimi’s neighbors and reportedly threw objects at the homes and tried to break into them.

French riot police were called to the scene to disperse the demonstrators, who left after singing the national anthems of both France and Israel and waving Israeli flags, Israel Radio reported.

Halimi was found dead April 3 on the street in front of her apartment in the crime-ridden 11th district of the French capital. Her 27-year-old neighbor, reported by Israel Radio to be Muslim, was later arrested in connection with her death. He has been sent for psychiatric evaluation, according to reports.

Relatives of Halimi said that she had previously experienced anti-Semitic harassment by a relative of the man under arrest. The woman was beaten before she fell from the third floor, Israel Radio also reported.

French police have not classified the woman’s death as a hate crime. French Jewish lawmaker Meir Habib asserted to Israel Radio Sunday that the woman was murdered because she was Jewish and not because her alleged killer is mentally ill.
